Methods for processing signals, communication devices, and computer-readable storage media.

Abstract

The invention reveals a method for processing signals, a communication device, and a storage medium readable by a computer. This method includes the following steps: The transmitting device generates a PPDU, where the PPDU includes the header, the header includes the LTF, which consists of LTF symbols, and the LTF symbols can be used to carry the received sequence according to the first matrix; and then send PPDU. In a corresponding manner, the receiving device receives PPDU, and then processes, according to the first matrix, the signals are received on LTK symbols. The first matrix is ​​the PnXn matrix, or the first matrix obtained according to the Pnxn matrix, where P11X]1 XP^xn = η XLI is the identity matrix, the pnxn matrix consists of n rows and n columns, the Prfxn matrix is ​​the transpose of the Pnx]1 matrix, and l is an integer greater than 8. According to the method proposed in the invention, Estimating channels with more than eight spatial streams can be performed.
